Abstract

Measurement of air pollution was observed by using Borland Delphi 7.0 program. This program displays the measured index of air pollution in circumtance condition.
The measurement of air pollution is used an gas sensor and a microcontroller AT89S51. This program used the microcontroller output then send it as serial
communication for being watch on the computer. Those index of pollution was carbon monoxide in the free air. Computer will process and display the measured index of pollution with chart, and displays air status on environtment
